No the branch with nothing on it is a gonner. As the frogspawn grows it "Y"'s, than the base of that new section hardens and becomes the branch. The branch becomes dead and is a support for the living coral. Break the branch, not the coral. Just grab it with both hands and give it a snap. Make sure every frag you break off has at least one full "Y" section and your good to go. EASY, I just did it for the first time a couple weeks ago and they look great.
